To all whom it may concern:

Be it known that I, ANTON ALBERT FEHE- ENBAoHEE, a citizen of the United States, residing at Condon, in the county of Gilliam and State of Oregon, have invented a new and useful Rotary Weed-Cutter and Cultivator, of which the following is a specification.

This invention has relation to rotary weed-cutters and cultivators; and it consists in they novel construction and arra ement of its parts, as hereinafter shown and esoribed.

The object of the invention is to provide a weed-cutter and cultivator having a central platform or frame which is adaptedto be adjusted vertically at its front and rear ends that is, two means of adjustment are provided and the said meansmay be operated independent of each other in order to give the platform the proper slant of inclination with relation to the surface of the ground. Triangular-shaped wings are hinged to the said platform, and each wing is provided with a meansfor adjustin the vertical position of its outer corner, sai means being operated from the platform. The platform and the wings are provided with a number of horizontally-disposed disks mounted upon shafts which are rotatably supported and which may slide longitudinally in their bearings.

. Tension-springs are provided to retain said shafts and their attachments in their lowermost positions. The said disks are slightly concaved and are of octagonal configuration. The supporting means of the forward end of the platform is pivoted thereto in order that short turns may be made with the imple- .ment.

In the accompanying drawings, Figure 1 is a top plan view of the weeder and cultivator.

- Fig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a rear end elevation of the same, and Fig. 4 is a transverse sectional view of one of the disks.

The frame 1 is pivotally attached at its forward end to the truck 2. Said truck is pivotally mounted upon'the bell-crank axle 3, the wheels 4 bein journaled at the lower ends of the bell-era thereof. The lever 5 is fulcrumed to the truck 2, and its working end is connected by means of the links 6' 6 with the bell-crank ends of the axle 3. The

power end of said lever passes up along the gear-rack 7 and is provided with the usual gear-engaging pin"& The said power end of the lever 8 is within operating distance of the drivers seat 9. The tongue or shaft 10 is at: tached to the truck 2. The arm 11 is pivoted at the rear end of theplatform 1 and is .provided with the rearwardly-exten .portion 12, to which is journaled the whee 13. The upper end of said arm 1 1.extends above the platform 1 and is connected by means of the link 14 with the lever 15. Said lever in turn ,is fulcrumed to the platform 1 provided with the usua v gear engaging'gisn 17. Said lever 15 is blSoinpperating tance of the drivers seat. 4

The gear-segment 23 is fixed to the 18 22 is provided with an ordinary gear-engaging the segment 23.

The'platform 1 is provided at an intermediate point and in its central lo 'tudinal axis with vertically extending disk-s ,afts 25. The disk 26 is fixed to the lower end of said shaft, and the said shaft is adapted to move vertically through the bearing 27, which is secured to the said platform 1.

spring 28 is interposed between the bearing 27 and the collar 29, attached to the s is such as tohave a tendency to maintain the .tions. The downward movement of the said which is adapted to engage-the upper end of the shaft-bearing 27. The wings 18 18 are which is fitted with a disk 26,- bearing 27', spring 28,collar 29, and enlarged'hea 30 The triangular wings 18 are hinged at one of said win s faces in the same direction as with the transverse axis of the said axle.-

provided with a number of shafts 25, each of concaved with the ed'ges disposed in a down-- at any suitable depthbelow the surface of 'nall'y inhorizontal each edge of the dis has a slight curve between the corners of the octagon.

.same contour, and a'descrition of one will answer for all. The said isks areslightly ward direction. The disks are cut octagolan,and consequently It-will thusbese'en that an implement is pro vided. for weeding and; cultivatin which uses disks of peculiar configuration orizontally disposed and which may be adapted to work the soil. The main platform is so mounted that it may be til-ted or slanted at either end, as conditions may require. The wings are hinged to the platform, so that they ma be raised or lowered at their outer ends, and the hinged connections with the platform afford a flexible implement which is adapted to adjust itself to the contour of the round. The various adjustments an movements of the parts are obvious and it is thought unnecessary to'explain them in detail here.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1 Animplement such asdescribed conwheels supporting the outer ends of said wings, a means for raising and lowering the outer ends of said win s, vertically-journaled shafts carried by the p atform-and wings and horizontally-disposed disks attached to the ends of said shafts.

' 2. An implement such as described consisting of a platform, wheels supporting said platform, a means for raising and lowering said platform, triangular wings hinged to the atform, wheels 5 longitudinal sides'of said p supporting the outerends of said wings, a

means for raisin and lowerin the outer ends of said wings, s afts vertical y journaled in said wings and platform and havin at their lower ends horizontally-disposed 'sks, the shafts and the win s being arranged in lines which extend parallel to the line representing the hypotenuse of the triangle of the wings.

. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of, two witnesses.
